The control end of the switch 300 is connected to the control module 100, and the common end of the switch 300 is connected to the input end of the detection module 200. Each sub-end is connected to the output end of each amplifying link, that is, the first sub-end of the switch 300 is connected to the output end of the first amplifying link 10, and the second sub-end of the switch 300 is connected to the first amplifying link. 10 is connected to the output terminal, the signal conditioning terminal of each amplifying link is connected to the control module 100, that is, the signal conditioning terminal of the first amplifying link 10 is connected to the control module 100, and the signal conditioning terminal of the second amplifying link 20 is connected to the control module 100. The control module 100 is connected; the control module 100 is configured to sequentially output a plurality of switching control signals at intervals of a preset time; the detection module 200 is configured to convert the output signal of the amplification link into a detection signal and output to the control module 100; switching The switch 300 is configured to switch under the control of the control signal to sequentially select one of the amplification links and the detection module 200 to connect with the detection module 200 at intervals of a preset time to enable the detection module 200 to access the output signal, that is, to sequentially gate according to the preset time interval.

应理解，控制模块100可以由微处理构成；检波模块200可由有具备检波功能的器件构成，例如检波管；切换开关300可以由具备多个分端以及至少一个公共端的开关器件构成，例如多路复用器、多路模拟开关或者多路射频开关等。It should be understood that the control module 100 can be composed of micro-processing; the detection module 200 can be composed of a device with a detection function, such as a detector tube; the switch 300 can be composed of a switching device with multiple sub-terminals and at least one common terminal, such as multiple channels. Multiplexers, multiple analog switches or multiple radio frequency switches, etc.
应理解，预设时间为间隔，可以根据多条放大链路所处的***的实际情况而设置。本实施例中的分时检测控制电路，切换开关300将各条放大链路的输出信号分时间段输出到检波模块200，由检波模块200分时间段将各个输出信号转换为 检波信号后，输出到控制模块100处理，实现对多条放大链路的分时检测和控制。It should be understood that the preset time is an interval, which can be set according to the actual situation of the system where the multiple amplification links are located. In the time-sharing detection control circuit in this embodiment, the switch 300 outputs the output signals of each amplifying link to the detection module 200 in time periods, and the detection module 200 converts each output signal into a detection signal in time periods, and then outputs It is processed by the control module 100 to realize the time-sharing detection and control of multiple amplification links.
本实施例中的分时检测控制电路，通过加入控制模块100、检波模块200以及切换开关300，实现了以预设时间为间隔依次选通检波模块200和一放大链路的连接通路，从而利用一个检波模块200和控制模块100实现对多条放大链路的分时检测和控制，解决了传统的技术方案中由于每个链路一般都需要一组独立的检波电路来实现对放大链路的检波而导致的检波电路数量多、整体电路复杂以及PCB尺寸大等问题。The time-sharing detection control circuit in this embodiment, by adding the control module 100, the detection module 200, and the switch 300, realizes that the connection path of the detection module 200 and an amplification link is sequentially gated at intervals of a preset time, thereby using A detection module 200 and control module 100 realize the time-sharing detection and control of multiple amplification links, which solves the traditional technical solution because each link generally requires a set of independent detection circuits to realize the detection and control of the amplification link. The detection caused by the large number of detection circuits, the complexity of the overall circuit, and the large PCB size.
在一个实施例中，控制模块100分别与各条放大链路的信号调节端连接，控制模块100还被配置为在接收到检波信号后，将检波信号与标准信号做比较，并根据比较结果输出用于调整到放大链路的工作参数。In one embodiment, the control module 100 is respectively connected to the signal conditioning ends of each amplifying link, and the control module 100 is also configured to compare the detection signal with the standard signal after receiving the detection signal, and output according to the comparison result Used to adjust the working parameters of the amplified link.
应理解，可以通过将检波信号的各项信号参数与标准信号的对应的各项信号参数一一比较，信号参数包括但不限于信号强度、信号大小、信号失真度等。控制信号对放大链路的控制方式可以为ALC(Automatic Level Control，自动电平控制)或者AGC(Automatic Gain Control，自动增益控制)。放大链路的工作参数包括放大参数、衰减参数等，即通过调整放大链路的放大参数或者衰减参数等工作参数，使得输入该放大链路的输入信号的各项信号参数在经过该放大链路的处理为输出信号后，该输出信号的信号参数与标准信号所对应的信号参数一致。It should be understood that the signal parameters of the detection signal can be compared with the corresponding signal parameters of the standard signal one by one. The signal parameters include but are not limited to signal strength, signal size, signal distortion, and the like. The control method of the control signal on the amplification link can be ALC (Automatic Level Control) or AGC (Automatic Gain Control). The working parameters of the amplification link include amplification parameters, attenuation parameters, etc., that is, by adjusting the amplification parameters or attenuation parameters of the amplification link, the various signal parameters of the input signal input to the amplification link are passed through the amplification link. After the processing is the output signal, the signal parameter of the output signal is consistent with the signal parameter corresponding to the standard signal.
可选的，在一个实施例中，还可以将检波信号的各项信号参数分别与预设的参数阈值作比较，然后根据比较后的各项比较结果汇总后生成控制信号。Optionally, in one embodiment, various signal parameters of the detection signal may be compared with preset parameter thresholds respectively, and then the control signal is generated after aggregating various comparison results after the comparison.
可选的，在一个实施例中，还可以通过将检波信号的各项信号参数分别与预设的参数阈值做差，将其差值与控制模块100中预存的标准差值范围做比较，根据差值落于预存的标准差值范围的位置来生成控制信号。Optionally, in one embodiment, the signal parameters of the detection signal can also be differentiated from preset parameter thresholds respectively, and the difference can be compared with the standard deviation range pre-stored in the control module 100, according to The difference value falls in the position of the pre-stored standard deviation value range to generate the control signal.
应理解，本实施例中的分时检测控制电路，通过根据检波信号与标准信号的比较结果生成控制信号，并通过该控制信号去调整对应的放大链路的输出信号的信号参数，从而实现对放大链路的输出信号的实时调整和控制，避免放大链路的输出信号由于外界信号干扰或者内部器件的损坏而失真或者不便于传输，同 时也使得放大链路的输入信号不一样时，其输出信号也为标准信号，避免了传统技术方案中由于放大链路的工作参数为固定值，而导致当输入信号的变化过大时，其输出信号也随之变化过大的问题。It should be understood that the time-sharing detection control circuit in this embodiment generates a control signal according to the comparison result of the detection signal and the standard signal, and uses the control signal to adjust the signal parameters of the output signal of the corresponding amplifying link, so as to achieve the Real-time adjustment and control of the output signal of the amplifying link to avoid distortion or inconvenient transmission of the output signal of the amplifying link due to external signal interference or damage to internal components. At the same time, when the input signal of the amplifying link is different, its output The signal is also a standard signal, which avoids the problem that when the input signal changes too much, the output signal also changes too much due to the fixed value of the working parameters of the amplification link in the traditional technical solution.
在一个实施例中，当检波信号的信号强度大于标准信号的信号强度时，控制信号用于控制放大链路增加当前衰减；当检波信号的信号强度小于标准信号的信号强度时，控制信号用于控制放大链路减少当前衰减；当检波信号的信号强度等于标准信号的信号强度时，控制信号用于控制放大链路维持当前衰减。应理解，当需要调整其他的信号参数时，其比较方式和调节方式可以参考本实施例。In one embodiment, when the signal strength of the detection signal is greater than the signal strength of the standard signal, the control signal is used to control the amplification link to increase the current attenuation; when the signal strength of the detection signal is less than the signal strength of the standard signal, the control signal is used to Control the amplification link to reduce the current attenuation; when the signal strength of the detection signal is equal to the signal strength of the standard signal, the control signal is used to control the amplification link to maintain the current attenuation. It should be understood that when other signal parameters need to be adjusted, the comparison mode and adjustment mode can refer to this embodiment.
应理解，控制信号控制放大链路增加或者减少当前衰减后，是使其衰减值参数增大或者减少为新的衰减值参数，在该放大链路增大或者减少为新的衰减值参数后，控制信号控制该放大链路一直保持该新的衰减值参数，直到下一周期对该放大链路进行新的检波并根据检波信号生成新的控制信号。It should be understood that after the control signal controls the amplification link to increase or decrease the current attenuation, it is to increase or decrease the attenuation value parameter to a new attenuation value parameter. After the amplification link is increased or decreased to a new attenuation value parameter, The control signal controls the amplifying link to keep the new attenuation value parameter until a new detection is performed on the amplifying link in the next cycle and a new control signal is generated according to the detection signal.
本实施例中的分时检测电路，通过将检波信号的信号强度与标准信号相比，并根据其比较结果去实时调整放大链路的衰减参数，进而实现了对放大链路的输出信号的信号强度的调节，避免了由于输出信号由于放大链路的衰减参数固定化而导致的信号强度过大或者过小的问题。The time-sharing detection circuit in this embodiment compares the signal strength of the detection signal with the standard signal, and adjusts the attenuation parameters of the amplifying link in real time according to the comparison result, thereby realizing the signal of the output signal of the amplifying link. The intensity adjustment avoids the problem that the signal intensity is too high or too small due to the fixed attenuation parameter of the amplifying link of the output signal.
在一个实施例中，当检波模块200没有与放大链路接通时，控制模块100持续输出上一预设时间的间隔内的控制信号到该放大链路。In one embodiment, when the detection module 200 is not connected to the amplification link, the control module 100 continues to output the control signal within the last preset time interval to the amplification link.
应理解，控制模块100一直分别持续输出对应的控制信号到对应的放大链路中，当切换开关300接通一放大链路与检波模块200的连接通路时，该放大链路的输出信号通过切换开关300输出到检波模块200的输入端中，检波模块200将该放大链路的输出信号转换为检波信号后输送到控制模块100，控制模块100根据该检波信号生成新的控制信号并输出到该放大链路，从而刷新对该放大链路的实时控制，与此同时，在该时间段内，其余的没有与检波模块200接通的放大链路，控制模块100分别持续输出上一个周期的控制信号到对应的放大链路中，即在该时间段内，控制模块100对没有被检波的放大链路的控制是维持原控制。It should be understood that the control module 100 has been continuously outputting corresponding control signals to the corresponding amplifying links. When the switch 300 turns on a connection path between the amplifying link and the detection module 200, the output signal of the amplifying link passes through the switch The switch 300 is output to the input terminal of the detection module 200. The detection module 200 converts the output signal of the amplification link into a detection signal and sends it to the control module 100. The control module 100 generates a new control signal according to the detection signal and outputs it to the Amplify the link, thereby refreshing the real-time control of the amplifying link. At the same time, during this time period, the rest of the amplifying links are not connected to the detection module 200, and the control module 100 continues to output the control of the previous cycle. The signal is sent to the corresponding amplification link, that is, during this time period, the control module 100 maintains the original control for the control of the undetected amplification link.
应理解，本实施例中的分时检测控制电路，在放大链路没有与检波模块200接 通时，控制模块100持续输出上一预设时间间隔内的控制信号到该放大链路，从而维持对放大链路的控制，保证对放大链路的全时段控制和分时段检波和刷新控制。It should be understood that the time-sharing detection control circuit in this embodiment, when the amplification link is not connected to the detection module 200, the control module 100 continues to output the control signal within the last preset time interval to the amplification link, thereby maintaining The control of the amplifying link guarantees the full-time control of the amplifying link and the time-division detection and refresh control.
在一个实施例中，检波模块200包括检波二极管或者检波芯片，应理解，当检波模块200包括检波二极管时，检波二极管的正极作为检波模块200的输入端，检波二极管的负极作为检波模块200的输出端。当检波模块200包括检波芯片时，检波芯片的检波输入端作为检波模块200的输入端，检波芯片的检波输出端作为检波模块200的输出端。In one embodiment, the detection module 200 includes a detection diode or a detection chip. It should be understood that when the detection module 200 includes a detection diode, the anode of the detection diode is used as the input terminal of the detection module 200, and the negative electrode of the detection diode is used as the output of the detection module 200. end. When the detection module 200 includes a detection chip, the detection input end of the detection chip is used as the input end of the detection module 200, and the detection output end of the detection chip is used as the output end of the detection module 200.
